What does coral bleaching refer to?

Coral bleaching refers to the phenomenon where coral loses its vibrant color and appears white due to environmental stress, particularly changes in temperature, light, and water quality. When corals are stressed, usually from rising ocean temperatures, they expel the symbiotic algae (zooxanthellae) that live in their tissues and provide them with nutrients and color. The loss of these algae is what leads to the bleached appearance of the corals. This stress can result from factors such as climate change, pollution, and ocean acidification. If the environmental conditions improve, there is a potential for the corals to recover, but prolonged bleaching can lead to coral death, affecting the entire marine ecosystem that relies on healthy coral reefs. The other options do not accurately describe the process of coral bleaching. Coral adapting to new habitats or gaining new colors does not relate to the stress-induced whitening. Additionally, coral reproduction, while it can occur in warm waters, is not a characteristic of bleaching itself.
